In the work consideration was given to investigation into the spectroscopic and nonlinear optical properties of photorefractive semiconductor cadmium telluride crystals doped with vanadium, ferrum and titanium. Introduction of dopants was required to produce an impurity absorption band in the near IR region and enhance the photorefractive properties. Two methods have been used for the production of doped crystals: diffused post-growth doping and growth of doped crystals from melt. Nonlinear optical properties of samples were studied at the wavelength of 1.06 micrometer in a four-wave mixing scheme. Maximum diffraction efficiency was revealed for the convergence angle of light beams approximating 8 degree, with the grating period of 7 micrometer and was equal to 2%. The dynamic grating lifetime was about 0.2 microseconds.
